. TACK-STRIP.

SPECIFICATION formingpart of Letters Patent No. 226,818, dated April 20, 1880.

Application filed March 19, 1880.

To all whom it may concern:

Be it known that we, ERASTUS WOODWARD andMATTHIAS BROOK, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented an Improvement in Tack- Strips, of which the following is a specification.

This invention is an improvement upon the tack-strips described in Letters Patent No.

186,663, dated January 30, 1877, and No.

197,609, dated November27, 1877, both granted to George W. Copeland and Matthias Brook; and it consists in the hereinafter-described provision given the tack-strip, whereby it may be fed by a suitable feeding mechanism to the driving device regularly and uniformly.

Reference is made to the accompanying drawings, forming a part of this specification, in explaining the nature of our invention, in

which Figure 1 is a perspective of our improved tack-strip. Fig. 2 is a modification of the'same. Fig. 3 is a plan of the strip shown in Fig. 1. Fig. 4 is a plan of the strip shown in Fig. 2.

Figs. 5 and 6, respectively, are cross-sections upon the lines or a: of Figs. 3 and 4.

In an application of even date herewith we have described a tack-strip having tack holding and connecting portion perforated or par- 0 tially perforated for the purpose of providing (No model.)

means by which the same can be fed bysuitable mechanism.

In this invention, instead of perforating the tack connecting and holding strip, we indent or recess one or both edges of the holdingstrip, and separate said indentations, grooves, or recesses by an interval equal in width to the distance between the tacks.

a represents the tack; I), the tack holding and connecting strip; 0, the indentations, grooves, or recesses. They may be arranged upon one or both edges of the strip, as desired, and in feeding it is designed that these indentations, recesses, or grooves shall act as abutments against which the feeding pawlor yoke which advances the strip horizontally to the tack-driving mechanism may come in contact.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States A tack-strip consisting of the tacks a and strip 1), having grooves or recesses 0 upon one or both edges thereof, substantially as and for the purposes described.
